Data Acquisition Modules, Data Acquisition Modules S304 , 4-Channel Pt Resistance Thermometer The DAM302 is for measuring 4-channel Pt resistance thermometer of PT100, PT500, PT1000, CU50, CU100 or other PT Resistance Thermometers and transmit in ASCII data format to any RTU, SCADA, data monitoring, data loggers, PLC? s, process controllers and instrumentation that supports Modbus RTU Protocol over RS485 serial port. Powered up by 10~ 30VDC. Introduction : The DAM302 is for measuring 4-channel Pt resistance thermometer of PT100, PT500, PT1000, CU50, CU100 or other PT Resistance Thermometers and transmit in ASCII data format to any RTU, SCADA, data monitoring, data loggers, PLC? s, process controllers and instrumentation that supports Modbus RTU Protocol over RS485 serial port. Powered up by 10~ 30VDC. The DAM302 is used widely in industrial automation temperature measurement systems. E.g.: Base Transceiver Station, diesel generator rooms, engine room, transformer substations, telecommunication equipment rooms, power supply systems and so on. The DAM302 is an industrial class, isolated designed, high reliability, low-power consumption, high stability and high precision data acquisition module. The DAM302 with fire retardant shell, standard 35mm DIN rail makes it easy to install in fields. Mainly Features: 24-bit resolution high precision AD acquisition and data processing techniques; Wide range power supply with reverse polarity connection protection; Modbus RTU Protocol; ESD Protection circuit for RS485 serial port; Using industrial-grade chips; Built-in watchdog ensure it reliability; Lightning protection ensure it stability; LEDs for status indication makes it easy to program in filed.
